kernels

i want to know that ...what iz d role of OS in compilation..and wht abt d kernels...wht do they do in dis process..????...howz compilation happening in mobiles..??

I have FC5(64-bit) installed on my system on my system(please system specs on my signature). I want to install the Cool 'n' Quiet driver for my OS as it tends to heat up if I leave it running for a long time. This doesn't happen on Windows. I don't know if this because of the driver which I have...

I have again installed the Fedora Core 3. It rocks. But it does not suport my internal modem which works fine on Windows. I also have a Conexant Modem which is damaged and itself gives very slow connection and the freeware Linuxant Driver only allow less than 14.4 Kbps and I get 2-4Kbps on that...
